I totally understand the degree of difficulty, even in one language, let alone all the supported languages. I guess it was wishful thinking on my part. I have been looking at my weak areas in Dutch and see this approach of highlighting verbs and verb parts, combined with full conjugations, as a big asset. I have been playing around with the concept by manually highlighting verbs and using Verbix. It really is useful, especially to learn conjugations without resorting to rote learning, to better understand word order in sentences, to understand separable verbs, and verbs being pushed to the end of sentences, such as in Dutch and German. I am going to see if I can implement some software to do the highlighting using a large corpus of conjugated verbs. The process will make a few mistakes but will probably be 95% correct with the highlighting and quick access to the fully conjugated verbs.

Thanks for your continued work on Readlang. I love it. I just wish I had more time to use it.
